History Of Bioethanol Presentation

  1. 1. The History And  Development Of  Bioethanol As An  Alternative Fuel  Christopher McAtominey
  2. 2. Overview  • What is bioethanol?  • Why bioethanol as an alternative fuel?  • The future of bioethanol
  3. 3. Ethanol  • Produced by hydrating ethylene or by  fermenting sugars  CH3CH2OH + 3O2  2CO2  + 3H2O  • First ever engine ran on ethanol  • Used as a rocket fuel in WW2
  4. 4. Bioethanol  •  Produced by fermenting sugars  •  Sugars are from natural sources (biomass)  eg sugarcane, maize  •  Burnt as fuel  •  Widely used in Brazil
  5. 5. Alternative Fuels  •  Climate change  •  Depletion of crude oil  •  Legislation
  6. 6. Alternative Fuels  •  Carbon neutral  •  Independence  •  Efficiency
  7. 7. Alternative Fuels Alternative Fuels 
  8. 8. Future of Bioethanol  • Currently only processed from sugars  • Aim is to convert all biomass to ethanol  • Engineering micro­organisms
  9. 9. GM  • Alcohol resistant yeast  • 1.5 x 10  tonnes of biomass is cellulose  12  • Cellulases convert cellulose into sugars
  10. 10. Problems  • Currently not carbon neutral  • Cellulases do not work well in vitro  • Predicted that hydrogen will be major  fuel of future
  11. 11. Fin  Any Questions?
